Abstract

This invention relates to novel polyol blends, a process for preparing foams with very low resistance to air flow from certain polyol blends and to the resultant foams. The polyol blends comprise one or more monofunctionai poiyethers having a hydroxy I number of less than 28; one or more polyether polyols having a hydroxy I number of 20 to 240 and containing at least 50% of copolymerized oxyethylene; one or more polyether polyols having a hydroxy I number of 47 to 300 and containing from 5 to 40% of copolymerized oxyethylene; and optionally, one or more polyether polyols having a hydroxy I number of 10 to 45. This process of the invention comprises reacting one or more polyisocyanates, with an isocyanate-reactive component which comprises a specifc polyol blend, in the presence of at least one catalyst, at least one surfactant and at least one blowing agent.
